METAL WHEEL.

To all whom it may concern:

Be it known that we, WILLIAM E. WIL- LIAMS and J OHN GRANT, each a citizen of the United States and a resident of Chicago, county of Cook, State of Illinois, have invented new and useful Improvements in Metal Wheels, of which the following is a specification.

Our invention relates to wheels especially adapted for baby carriages and other light vehicles but usable for \heavier work.

The general object of the invention is to provide a serviceable wheel of neat appearance and low cost that may be readily made by automatic machinery. In the accompanying drawings, Figure 1 shows the wheel in side elevation. Fig. 2-is an axial section of the wheel. Fig. 3 is a detail view showing a portion of the wheel hub. Fig. 4 shows in view a certain rim joint. section.

The rim, 2, of the wheel is curved in cross section so that it may receive a rubber tire. it is not integral but its ends abut and one is provided with at least one projection 11 to enter a corresponding recess in the other.

Strips 10 arecpuinched inwardly at inttrvals along the me ortion of the rimtc form eyes through whic spokes may be threaded. The rim joint is at one of the equidistant points where thespok'es are to meet the rim, and here instead of an eye 10, there is a clip 13 having its middle bent inward like the eyes, and with its ends assed through apertures 12 in the rim and c enched or bent down snugly upon the body of the rim, thereby holding the ends firmly together as well as in perfect alinement.

The hub consists ofan outer tube 5 having notches 9 in each end, a longer and smaller inner tube 6, and annular flanged caps 7 To form the s okes, rods 3 are passed through the eyes 0 the rim until the middle of each lies in the correspondingeye, the end portions ofeach are then bent sharply, at the eye, until each branch maylie in one of the notches in the corresponding end of the outer hub tube 5, and each branch is bent sharply inward at such'point that the terminal portion may with slight difiiculty he pusheo into this tube. The spokes being all thus put in position, the inner tube is put 1n place, its external diameter being such that Fig. 5 shows the same joint in the ends of the spokes are firmly held between it and the outer sleeve, and the threaded caps 7 are then screwedupon the threaded ends of the inner tube to meet the ends of the outer tube and at the same time to force the spokes firmly against the bottoms of their notches. The ends of the inner tube, which is made long enough for the purpose, are then swaged or spun outwardly over the caps at 14 rigidly and permanently binding the parts together. I

It is of course-not indispensable that the rim be adapted to receive a round rubbertire, nor that the caps be threaded upon the inner hub tube, nor that the s okes have the two parts in the same place, ut the precise through the two annular caps and flanged n g-d ends of the spokes, extending out down upon the latter, binding the partstogather rigidly.

A discontinuous metal rim having its ends abutting-and interlocked combined with a clip extending across the joint, hav' its middle bent inward to form a spoke ing eye, and having its encs lccln-vd in ertures in the rim ends.

3. In a metal Wheel, the cinnbination with a straight outer hub tubewi'lh spoke-receiv ing notches in its ends, of a smaller c trio inner tube projecting beyond the e the outer tubes, spokes lying in said lllii ililes and bent sharply into the annular space between the tiibes, closely fitting therein and forming the only obstructions in the annular space, and heavy annular caps slipped upon e projecting ends of the inner tube and pro: vided with flanges fitting over the notched end portions of the outer tube; said projecting .ends being spun or swaged down upon the caps, substantially as set forth.
